Chapter 6 – Tips, General Information, and Known Issues
Using the Twin10G Adapter to Charge Your Notebook or
Laptop Computer
Apple
®
MacBook Air
®
and MacBook Pro
®
computers with
Thunderbolt 3 and some PC laptops with Thunderbolt 3 may be
charged slowly via the Twin10G adapter’s Thunderbolt 3 port, but
some PC laptops will not accept charging from a Thunderbolt
peripheral; see https://gtrusted.com/technology/thunderbolt/
thunderbolt3-hosts/ for more information. Computers with
Thunderbolt 2 or Thunderbolt ports may not be charged via
Thunderbolt.
KNOWN ISSUES
Not All Computers’ Thunderbolt 3 Performance is Equal
While this product features a 40Gbps Thunderbolt 3 interface,
some computers equipped with Thunderbolt 3 use an
implementation of Thunderbolt 3 that limits PCIe performance
to 20Gbps. Mid-2017 and earlier 13-inch MacBook Pro computers
with four Thunderbolt 3 ports have this limitation in the two
right-hand Thunderbolt 3 ports, while offering full performance
from the left-hand ports.
Not All Thunderbolt 3 Cables Deliver Full Performance
Full performance from the Twin10G adapter requires the use of
the included Thunderbolt 3 (40Gbps) cable (which also supports
up to 100W power delivery), or a comparable Thunderbolt 3 cable.
When shopping for a Thunderbolt 3 cable, please be aware that
some support only lower data transfer speeds (20Gbps).
Operating System (OS) Updates May Break Compatibility
Specific device drivers that work under one OS version may not work
under a later version. Before updating your computer to the latest OS,
we recommend that you contact Sonnet support pages to verify
that the existing drivers work. Note that other software updates
for the computer may also break compatibility.
Some Devices’ Performance May be Affected by Where They
Are Connected in a Thunderbolt Chain
However small, Thunderbolt introduces latency to a device chain.
If you add additional Thunderbolt devices to the chain, you may
need to experiment with positioning devices closer to or farther
from the computer in the chain.
TIPS, GENERAL INFORMATION
Keeping the Twin10G SFP+ T3E Adapter Cool
With its optimized airflow design and automatic, temperature-
controlled fan providing cooling at all times, the Sonnet adapter
provides adequate cooling for the components inside. Do not block
the fan or any of the vents while the adapter is operating! Otherwise,
the adapter may overheat.
Hot-Plugging the Twin10G SFP+ T3E Adapter
You may connect and disconnect the Thunderbolt cable between
the Twin10G SFP+ T3E adapter and your computer while your
computer is on.
There’s No Need to Unplug the Power Adapter
Because the Twin10G SFP+ T3E adapter automatically powers
on and off with the computer to which it’s connected, there’s
no power switch, nor is there any need to disconnect the power
cable under normal use. When your computer is sleeping, the
Twin10G SFP+ enters a low-power state; this allows it to wake
with your computer.
Power Indicator LED Operation
Because the Twin10G SFP+ T3E adapter automatically powers
on and off with the computer to which it’s connected, its power
indicator only lights when the computer is on, and turns off
when the computer is sleeping or powered off. Note that the
power adapter’s power indicator remains lit as long as it is
connected to a live power outlet.
Connecting Additional Thunderbolt 3 Peripheral Devices
The Twin10G SFP+ T3E adapter includes two Thunderbolt 3
ports; the first connects it to your computer, while the second
supports daisy-chaining of up to five additional Thunderbolt
peripheral devices.
Twin10G SFP+ T3E Provides Upstream Power
The Twin10G SFP+ T3E adapter can provide up to 15 watts to
bus-powered Thunderbolt 3 peripheral devices, enabling them to
operate without connecting an additional power adapter.
How to Identify Thunderbolt 3 (40Gbps) Cables
Look for the Thunderbolt icon (
) AND the number 3 on
the connector housings to identify these cables. Cables with
USB-C connectors that only have the Thunderbolt icon without
the number 3 may only support 20Gbps speeds, and are not
recommended for Thunderbolt devices with high bandwidth
requirements. Cables marked with the USB icon (
) are NOT
compatible for connecting the Twin10G adapter to the computer.
